SELF-LIGHTING DEVICE FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 633,405, dated September 19, 1899.

Application filed May 24,1899. Serial No. 718,091. (No model.)

To c//ZZ whom t nm/y concern Beit known that I, ERNST 'VIESE, a citizen of the Empire of Germany, residing at Berlin,

`in the Kingdom of Prussia, in the Empire of Germany, have invented a new and useful Self-Lighting Device for Gas-Burn ers and the Like, of which the following' is a specification.

The self-lighting devices hitherto known having a piece of spongy platina and applied to the top of the chimney of gas-burners, especially incandescent gas-light burners and the like, have not proved successful, because the spongy platina, though not glowing any more after kindling the dame, yet is very'7 soon spoiled through the combustion products constantly arising, and is thereby rendered unfit for use.

My invention relates to a new self-lighting device; and the objects of myinvention are, first, to provide a hole in a cap placed at a certain height above the chimney-top for yallowing of the gas passing through and getting at the piece of spongy platina above the hole in order to be thereby lighted, and, secondly, to provide a ilap, valve, or clack-valve pivoted at` the bottom side of the cap and leaving the hole open until the gas is turned ion and lighted and arranged for closing the hole, when being acted upon by the arising combustion products, after the hindling of the flame, so as to lead ofi the combustion products along the bottom side'of the cap to the outside, and thus to keep them off from the spongy platina, which always retains its position at the proper place .for hindi-ing the filame. The piece of spongy platina will then last muc-h longer and retain its lighting power. 4 The new self-lighting device is illustrated in the accompanying drawings, in which* Figure l is a vertical section of the device having a conical cap placed above the top edge of the chimney, the clack-valve being shown in the open position. Fig. 2 is a vertical section of the same device, the clackvalve being shown in the closed position. Fig. 3 is a vertical section of a modication of the device in which the cap is made flat and arranged in a slanting position. Fig. 4

is a vertical section of another modification of the device in which the nat cap is placed'horizontally above the top edge of the chimney.

Similarletters refer to similar parts throughout the several views.K

The conical cap g of the device shown in Figs. 1 and 2 has adiametcr somewhat larger than that of the chimney and is ixed at a certain height above the top edge of the chimney in some known manner-for example, by a fork s, as shown, orseveral forks, the prongs of which reach over the inside and the outside walls ofthe chimney. The conical cap g may be made of mica or other suitable material and be provided with a hole Z near the top corner. From a piece of wire b, fastened on the cap g, is suspended a piece of spongy platina p, which points at the center of the hole l. At the bottom side ofthe cap g a-clackvalve 7c is pivoted at a, which is preferably balanced to a certain extent by a counterweight r, arranged on the lever n. so as to open the hole Zwhen the gas is not lighted and to close the hole Z when acted upon by the com bustion products after the hindling of the flame. Thus on turning the gas on the clackvalve k is open and allows of the gas going through the hole Z and passing freely the spongy platina p, which will light the gas. After the kindling of the llame the arising comb ustion prod nets will close the clack-valve` 7u, (se'e Fig. 2,) and hence they will be conducted along the bottom side of the cap g to the outside., the spongy platina p being now kept out of reach of the hot combustion products.

In the modification of the device shown in Fig. the flat cap g is arranged in a slanting position at a certain height above the top edge of the chimney This cap g has its hole l in the center, and the piece of spongy platina p, suspended from a wire h or other support on the upper side of the cap g, again points at the center of the hole I. The clach-valve may be pivoted at the uppermost point of the cap g at a and arranged to hang down ward in a slanting position when open, as is shown by the dotted lines, so that the gas upon turning the cock on may easily arise in the chimney .e to the hole land get at thespongy platina p to be thereby lighted.

In the device shown in Fig. ai the cap g, arranged horizontally, may be supported by arms s s, projecting from a ring t, placed on IOO the top edge of the chimney 2'. The arrangement of the hole l, the piece of spongy platina p, and the clack-valve 7c are the same as before.

In general the cap g, above the chimney-top, may be shaped in some suitable style and according to the circumstances without deviating from the principle of my invention. It may be conical, tunnel-like, cup-like, even, and so on. As to the clack-valve, fla-p, or valve 7o the counterweight r is preferably made adjustable, so as to balance the valve or iap to a nicety. For the valve or flap 7s, the shape of which may be of any kind, it is essential that it should be acted upon by the arising hot combustion products in such a manner as to close the hole Z under the piece of spongy platina p and lead off the gases. The manner of operating the valve or iiap lc may also be altered to suit the circumstances. It is only necessary to so arrange the device that after the kindling of the gas the combustion products are kept off from the spon gy platina.

What I claim as my invention, and desire to secure by Letters Patent, is-
